COBRA INTERNAL ERROR / ArgumentException / An item with the

[gauthier]

I get internal error when compiling dll with many dependencies (nhibernate, activerecord, windsor...)

Code: Select all

error: COBRA INTERNAL ERROR / ArgumentException / An item with the same key has already been added.

the compiler arguments look like that:

Code: Select all

-t:lib
-color
-d
-out:%PROJECT%\build\net-3.5\debug\bdabd.BusinessLogic.Billing.Implementation.dll
-ref:%PROJECT%\build\net-3.5\debug\castleproject\bin\Castle.Core.dll

-ref:%PROJECT%\build\net-3.5\debug\projectlib4.dll
-ref:%PROJECT%\build\net-3.5\debug\projectlib5.dll
%PROJECT%\...\source.cobra

some projectlibs are cobra assemblies

This is after having progressively added needed dependencies to the build script, I also got FileNotFoundException when dependency order doesn't suit cobra well (when same order is working with csc).

Anyone encounter theses issues with large solution?

anyway to diagnostic how cobra parse references?

[Charles]

Try adding:

cobra -v:3 -reveal-internal-exceptions ...

[gauthier]

Sadly, for my particular case, the additional arguments doesn't show any detail for the exception.

What I see is that the order of dependencies is tweaked from the order given in the command line.

The argument exception does'nt say more.

It worth mentioning that some assemblies (c# or cobra) contains the same namespaces.

[Charles]

-- Are you using the latest source or the last release (0.8)?

-- It would be highly unusual for -v:3 not to show additional output. Also, it would be unusual for -reveal-internal-exceptions to leave the message as "COBRA INTERNAL ERROR / Argument Exception / ..." instead of dumping the exception stack to the console. Consider this program:

class X

    def main is shared
        pass
%% throw

When run from the command line as:

cobra -v:3 -reveal-internal-exceptions internal-error.cobra > r 2>&1

The output captured in r is:

Well we're closer to understanding. Cobra thinks there is a duplicate member declaration in a type in lib11.dll. But there are a few dictionaries being updated in that method.

When Cobra is installed, it's compiled with -turbo which turns off contracts and other checks. I've just checked in an enhancement so you can say:

install-from-workspace -debug

And the "-debug" will replace the -turbo. Be sure to do an svn up first, the install and then try again.

The problem is reproducible by referencing 2 assemblies containing a same namespace part without the same case:

lib1.cs

Code: Select all

namespace Name1 {public class Foo {}}

csc /target:library lib1.cs

lib2.cs

Code: Select all

namespace name1 {public class Bar {}}

csc /target:library lib2.cs

class Program
    def main is shared
        pass

cobra -ref:lib1.dll -ref:lib2.dll main.cobra

[Charles]

Thanks for distilling this down. I'll fix.

Btw is this something that you corrected after you found it, or do you really want two namespaces that differ by case only? I'm curious how/why this comes up.

[Charles]

I checked in some improvements. Update and try again.

[gauthier]

Btw is this something that you corrected after you found it, or do you really want two namespaces that differ by case only? I'm curious how/why this comes up.

I took ownership of horrendous codebase and decided the new architecture (working with existing app runtime) took place in the same namespace with first part as lowercased, this is edge but realworld case (you can't avoid someone being to create "system" or anything).
